Estimation Method Based on Extended Kalman Filter for Uncertain Phase Shifts in Phase-Measuring Profilometry
Phase-measuring profilometry (PMP) is increasingly applied in high-accuracy three-dimensional shape measurement.However, various factors may result in the uncertainty DANDRUFF/DRY SCALP CONDITIONER of phase shift values in the PMP system, and phase errors induced by actual phase shift often bring about the reconstruction failure of a measured objec
